Undefined method `ferret_rank='

Philip_Ingram · June 4, 2009, 12:38am

i am getting the following error message using the AAF gem version
0.4.4 in my rails app.

undefined method `ferret_rank=’ for #Page:0x246060c

i"m using multi search but i have the same code working on another
app, using the plugin. To me this method looks like it’s missing from
the gem version, but is that possible?

I have an index compiled, but this error appears whenever i search for
something in the index. when i search for terms not in the index, it
works as expected,… nothing is returned.

More trace stack:

Thoughts???

i am not using multi search, i meant to write i am using a shared
index, but it only had ONE model in it for now. although that still
doesn’t seem to make a difference.

sorry for the confusion.

Did you manage to solve this issue. I have exactly the same error using
the shared index in config/aaf.rb

In the console I rebuilt the indexes for the relevant 3 models I am
using.
I do an example search in the console:

results = ActsAsFerret.find(“pete*”, ‘shared’)

I get results back perfectly.

When I do it in the application I get

undefined method ferret_rank=' for <2nd model in my list> /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/attribute_methods.rb:255:inmethod_missing’

Can anyone help I am banging my head against a wall

Thanks in advance.

I spoke to Jens who was on vacation - thanks a lot mate, really
appreciate your help. It appears that this happens when the model is not
extended properly.

Solutions:
– Use the plugin rather than the gem. This fixed it for more straight
away.
– require config/aaf.rb in your environment.rb

Hope this helps some one.
